CONSTRUCTION SWPPP CHECKLIST - azdeq.gov

1 2008 CONSTRUCTION General Permit SWPPP Guidance CHECKLIST This optional CHECKLIST is provided to assist owners and operators in preparing their AZPDES stormwater pollution prevention plan ( SWPPP ) to meet the requirements of Arizona s 2008 CONSTRUCTION General Permit (AZG2008-001). The Descriptions provided below do not necessarily reflect the exact wording used in the permit; rather these are stated in simplified language to provide additional guidance. (Note if any inadvertent conflict exists between this document and the permit, the permit language prevails). The Permit Citation column shows you where each particular requirement is found in the 2008 CGP. Use the Location column to note the page where the requirement is addressed in your SWPPP .

2 Please leave the For ADEQ Use Only column blank. Using this SWPPP CHECKLIST will help you ensure that all the permit requirements are addressed in your SWPPP and will also assist the Department in conducting a more efficient review of your SWPPP if it is required to be submitted. Please note that your SWPPP does not have to follow the format of this CHECKLIST ; the purpose of this CHECKLIST is only to ensure that your SWPPP contains all required components. While this CHECKLIST is intended for use in preparing your initial SWPPP , your SWPPP is a living document and it is important that it be updated to document changes in your project, best management practices (BMPs), Inspections, and other pertinent information. Permit Citation Description Location in SWPPP & Notes For ADEQ Use Only OPERATOR RESPONSIBILITIES Part Identify who is responsible for on-site SWPPP implementation Part Indicate or show the areas of the project where the operator has control over project specifications, including the ability to make changes in specifications Part Provide name(s) of the person(s) who have day-to-day control over CONSTRUCTION plans and specifications Part Identify who is responsible for installing, implementing, and maintaining the BMPs in the plan Part Identify or show the areas of the project where each operator has control over day-to-day activities Part Provide name(s) of the person(s)

3 Having control over project specifications, including the ability to make changes in specifications Part Provide the name and contact information for all operators and indicate the areas of the project each operator controls PROJECT DESCRIPTION Part Identify all potential sources of pollutants/ pollution from CONSTRUCTION activities that could possibly contact stormwater Part Describe the CONSTRUCTION activity (what is being built, what is being disturbed, how long it is expected to take, etc.) Part Describe the project and what it will be used for when completed (after Notice of Termination (NOT) is filed) AZPDES CONSTRUCTION SWPPP CHECKLIST 1 May 2008 AZPDES CONSTRUCTION SWPPP CHECKLIST 2 May 2008 Permit Citation Description Location in SWPPP & Notes For ADEQ Use Only Part Describe the planned phasing or sequencing of land disturbance activities.

4 The amount of open/disturbed dirt left open at one time should be minimized where possible Part Indicate the total acres of the site and number of acres that will be disturbed (include off-site borrow and fill area, staging and equipment storage areas) Part Indicate the percentage of the site that is impervious ( , paved, roofed, etc.) before and after CONSTRUCTION Part III Describe the soil ( , sand, clay, etc.) at the site and its potential for erosion (Suggestion: reference the Soil Survey covering the project site prepared by the Department of Agriculture, Natural Resource Conservation Service for soil information ) Part Include a map showing the project location ( quadrangle, portion of a city or county map).

5 The map must also show any washes or other waterbodies within 1 mile of the site Part Identify the nearest receiving water(s). A receiving water is a natural watercourse into which stormwater would flow in a storm event and includes dry washes, streams, tributaries, and other waters of the (such as designated canals). Man-made structures such as retention basins, storm sewer systems, or city storm drains are not receiving waters. Part Identify the areal extent where soils may be disturbed and show any wetlands near the site that could receive dirt or run-off from the CONSTRUCTION activity Part Describe any pollutant sources from areas other than dirt moving ( , dedicated concrete and asphalt plants, fueling operations, material or waste storage etc.)

6 That are associated with the CONSTRUCTION project). Identify where these sources are or will occur on site SITE MAP (note multiple maps may be used) All the following are to be shown on the site map or maps Part Include a site map completed to scale Part Use arrows to show the direction(s) where stormwater will flow for all areas within the project limits (This is for the period during CONSTRUCTION , not final contours. Flow direction may change as project grading progresses; when this occurs, maps are to be updated.) Part Show areas of soil disturbance and areas that will not be disturbed Part Show all structural BMPs identified in the SWPPP Part Show locations where stabilization BMPs are expected to occur Part Show locations of on-site material storage, waste storage or receptacles, borrow areas, equipment storage or other supporting activities AZPDES CONSTRUCTION SWPPP CHECKLIST 3 May 2008 Permit Citation Description Location in SWPPP & Notes For ADEQ Use Only Part Identify any water bodies (including dry washes and wetlands) on the site.

7 If there are no water bodies, indicate this on the map Part Show locations where stormwater discharges to surface water (including wetlands, ephemeral waters and dry washes) and to municipal storm sewer systems (MS4s) (use an X to indicate discharge location(s)). Where surface waters and/or MS4s receiving stormwater do not fit on the map, use arrows to show the direction and indicate the approximate distance to the surface water and/or MS4 Part Show the location and registration number of all onsite dry-wells and dry-wells located on adjacent properties that could receive stormwater from the site (if none exist, indicate that) Part Identify any areas of the site where final stabilization has been achieved Part Specify existing vegetated areas (trees, brush, etc.)

8 And boundaries of environmentally sensitive areas and buffer zones that are to be preserved BMP (Best Management Practices) REQUIREMENTS Part , , and Identify BMPs selected for the site and describe how each will reduce pollutants in stormwater Part Describe how BMPs will be added, modified, or replaced for each phase or sequence of CONSTRUCTION activities. Also, identify which operator is responsible for the implementation of BMPs Part Provide drawings and/or specifications of structural BMPs that include design or installation details Part Describe where natural/existing vegetation will be preserved. Locations of trees and boundaries of environmentally sensitive areas and buffer zones to be preserved are also to be on the SWPPP site map Part If using seed to revegetate, provide the mixture and application specifications.

9 (These may be obtained from product provider) Part If culverts are present on-site, describe measures that will be used to minimize erosion at and around the culvert(s) Part Describe how off site stormwater that may run onto the project site will be diverted or otherwise managed with on-site engineering controls, containment, or BMPs Part Identify how records of dates when major grading activities occur will be kept Part Identify how records of when CONSTRUCTION activities temporarily or permanently cease on all portions of the site will be kept Part Identify how records of when stabilization measures are initiated and completed and reason(s) for delay will be kept AZPDES CONSTRUCTION SWPPP CHECKLIST 4 May 2008 Permit Citation Description Location in SWPPP & Notes For ADEQ Use Only Part Provide sizing criteria and show calculations for sediment basin(s) and indicate whether basin(s) will be temporary or permanent ( , post- CONSTRUCTION ) Part Provide reason(s) or rationale why a sediment basin was determined to not be possible at the project site (If applicable) Part Describe the location(s) and how materials will be stored or staged both on-site and offsite.

10 Including overburden, soil stockpiles, and borrow areas Part Identify and provide the location(s) of all non- stormwater discharges allowed by this permit expected to be associated with the project and describe BMPs used to minimize discharge of pollutants Part Describe measures for preventing and responding to spills, including spill notification requirements POST- CONSTRUCTION CONTROLS Part Identify post- CONSTRUCTION stormwater BMPs ( , porous pavement, open space preservation, etc.) that will be installed as part of this project.
